Each session is a separate 10,000-spin window extracted from a continuous dataset of 393,491 paid spins. Five sessions were selected to represent the full range: the best outcome, the worst, the most statistically typical, the session with the most bonus triggers, and the one containing the largest single win.
The outcome range is 29.18 percentage points. At a £2 stake across 10,000 paid spins, the gap between Session 1 and Session 2 amounts to roughly £580 in total return.
Across 50,766 total spins in these five sessions, the zero-win rate held between 57.2% and 57.8%. Session 1 (113.34% RTP): 57.3%. Session 2 (84.16% RTP): 57.8%. Session 4 (105.88% RTP): 57.2%.
A 0.6-point range, across sessions that differ by 29 points of total return, is not statistical noise. It is the base game mechanic behaving exactly as designed. Sweet Bonanza returns nothing on roughly 57 of every 100 spins regardless of where the session ends up. No session in this dataset produced a sustained run of base game wins that meaningfully shifted this figure.
The base game is not where outcomes are decided.
| Session | RTP | Bonuses | Frequency | Max Win |
|---|---|---|---|---|
| 1 — Highest RTP | 113.34% | 28 | 1 in 357 | 547x |
| 2 — Lowest RTP | 84.16% | 16 | 1 in 625 | 146x |
| 3 — Closest to cert. | 96.36% | 20 | 1 in 500 | 347x |
| 4 — Most bonuses | 105.88% | 33 | 1 in 303 | 320x |
| 5 — Biggest win | 103.70% | 27 | 1 in 370 | 1,193x |
Bonus frequency ranged from 1 in 303 (Session 4) to 1 in 625 (Session 2). Every significant win in every session came from a free spin round. The base game, across 50,766 spins, was responsible for none of the sessions' value above the mechanical floor.
Session 2 averaged one bonus every 625 paid spins — 43% slower than Session 4's 1 in 303. The RTP difference between them: 21.72 percentage points. Zero-win rate in Session 2: 57.8%. In Session 4: 57.2%. The base games were essentially identical. The entire RTP gap came from how often free spins activated.
Session 5 contains the largest win in this five-session subset: 1,192.5x at paid spin 5,043. At £2 per spin, that produced £2,385 from a single free spin round.
Despite that, Session 5 did not produce the highest RTP. It finished at 103.70% — third among the five. Session 1 reached 113.34% without a win above 547x, accumulating its result through consistent free spin performance across 28 bonus rounds. One extreme win does not determine session outcome. Distribution across bonus frequency does.
Session 2 received 16 bonuses across 10,000 paid spins — one every 625 spins. Session 4 received 33 — one every 303 spins. Both sessions used a £2 stake and produced the same 57% zero-win base game. Session 2 finished at 84%. Session 4 at 106%.
The difference between a losing session and a profitable one in this dataset came entirely from how often the free spin mechanic activated — and how richly it paid when it did.
The longest losing streak across the five sessions was 17 consecutive zero-win paid spins, recorded in Session 3. At 50 spins per hour, that streak represents roughly 20 minutes of consecutive losses with nothing visible in the base game.
Expected cost to first bonus at dataset average frequency (1 in 438): 437.7 spins x £2 = £875 expected cost
Range observed across these five sessions:
A player with a £200 session budget at £2/spin covers 100 paid spins. At dataset average bonus frequency of 1 in 438, that budget does not reach the statistical expectation for a single bonus trigger.

At 10,000 paid spins per session, variance is still substantial. The five sessions averaged 100.69% combined — closer to the certified figure. At 393,491 spins, the full dataset converges to 96.9%.
It is determined by the base game probability tables — specifically by how many symbol combinations produce a cluster win. Sweet Bonanza's base game produces no cluster on approximately 57.2% of spins. This proportion does not change based on session outcome, bonus frequency, or any session-level variable.
Not directly. Session 4 received the most bonuses (33, 1 in 303) and finished at 105.88%. Session outcome also depends on what each bonus pays. A session with 33 bonuses that each pay poorly will underperform a session with 27 bonuses that include a 500x+ free spin round. Both variables — frequency and per-bonus payout — determine the result.
In this dataset, every win above 50x occurred during a free spin round. The base game tumble mechanic produces small wins in the 0.1x to 5x range that partially offset losses between bonus triggers, but the cumulative base game contribution is negative. The free spin multiplier stacking mechanic is where all meaningful value originates.
Session 2 averaged one bonus every 625 paid spins at £2/spin — approximately £1,250 expected cost between bonus triggers at that frequency. A player starting with a £500 budget could reach this threshold and receive no bonus at all. The bust threshold depends on the actual bonus frequency experienced, not the long-run average.
